Sslstream Read возвращает 0 ⇐ C#

[Anonymous]

У меня есть странная проблема с SSLStream в моем приложении. закрыт)
То же приложение, которое работает на той же ОС (Windows 11 23H2) в той же сети, работает правильно. тот же сервер.
Есть идеи? p>
Authenticated: true
protocol: tls12
cyphersuite: tls_ecdhe_rsa_with_aes_128_cbc_sha256
LeaveInnerStreamoPen: false < /p>
_tcpClient = new TcpClient();

_tcpClient.ReceiveTimeout = 40000;
_tcpClient.SendTimeout = 40000;
_tcpClient.ReceiveBufferSize = 40000;

UInt32 on = 1;
int size = sizeof(UInt32);
UInt32 keepAliveInterval = 1000;
UInt32 retryInterval = 100;

byte[] inArray = new byte[size * 3];
Array.Copy(BitConverter.GetBytes(on), 0, inArray, 0, size);
Array.Copy(BitConverter.GetBytes(keepAliveInterval), 0, inArray, size, size);
Array.Copy(BitConverter.GetBytes(retryInterval), 0, inArray, size * 2, size);

_tcpClient.Client.IOControl(IOControlCode.KeepAliveValues, inArray, null);

_tcpClient.Connect(HostName, Port);

_stream = new SslStream(_tcpClient.GetStream(), false, (object sender, X509Certificate? cert, X509Chain? chain, SslPolicyErrors policy) => true);
_stream.AuthenticateAsClient(HostName, _certs, SslProtocols.Tls12, true);

Console.WriteLine($"Authenticated: {_stream.IsAuthenticated}, HostName: {_stream.TargetHostName}, CypherSuite: {_stream.NegotiatedCipherSuite}, Protocol: {_stream.SslProtocol}, LeaveInnerStreamOpen: {_stream.LeaveInnerStreamOpen}");

_stream.Write(reqBytes);

request.OnRequestSent(Timestamp.GetTimestamp());

while (!_tcpClient.Client.Poll(1000000, SelectMode.SelectRead))
{
if (_internalState != InternalState.Started)
return null;
}

byteReads = _stream.Read(dataReceiv, 0, dataReceiv.Length);

if (byteReads == 0)
throw new Exception("Socket read error");
